The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

In this paper, the authors report on the importance of using Intensive Interaction for the development of non-verbal communication for people with autism. The complexity of learning non-verbal communication means that it cannot be taught in any sense in a traditional, didactic manner. While a person may have the cognitive abilities to follow instructions and be taught the need to behave a certain way in social situations, which will not allow them to properly assimilate and understand social expectations and how to operate in social contexts. This paper suggests that the use of Intensive Interaction creates frequent opportunities for a person to take part in face-to-face interactions and consequently allow for the gradual development of non-verbal communication. 相似文献

Prior to the exhibition Portrait-making, Rodin and his models (2009), the Rodin museum wanted to restore two busts of Hanako and Clemenceau. Interestingly, these two sculptures contain pieces of modern modeling materials (MMMs) invented at the end of the nineteenth century as an alternative to clay or waxes. The poor state of conservation of the two portraits made any handling and exhibition impossible. Accordingly, the purpose of this article is twofold: to contribute to technical art history and conservation. Elemental and chemical analyses were done on samples from 12 sculptures (SEM–EDX, FTIR, GC–MS, GC–FID, XRD, synchrotron-based µXRF, µXANES, and µFTIR) aimed at identifying the composition of MMMs used by Rodin on plaster sculptures and establishing hypotheses about the origins of their degradation. This thorough study of their composition and degradation was necessary to implement an appropriate restoration plan. The development of conservation protocols adapted to such materials is rarely documented. Different tests were performed on mock-ups (pH, solubility, adhesion, consolidation, and cleaning). In particular, a protocol based on laser cleaning was developed and successfully applied to remove superficial dust and crusts so that the sculptures regained their original aspect. 相似文献

Learning environments at the margin: Case studies of disenfranchised youth doing science in an aquarium and an after-school program 总被引:1,自引:0,他引:1
In this article, we explore how two informal educational contexts—an aquarium and an after-school science program—enabled
disenfranchised learners to adopt an identity as insiders to the world of science. We tell the stories of four youth, relating
what doing science meant to them and how they positioned themselves in relation to science. We contribute to the extensive
literature on the value of learning beyond the school walls, yet focus on ethnically and linguistically diverse youth from
low-income backgrounds who have often been excluded from such settings. We suggest that such out-of-school settings are particularly
important to youth who have few other opportunities to interact with and relate to science in positive ways. 相似文献

Fault finding is a puzzling task, at work and in technical and professional training. Our purpose is to contribute to an analysis of the required competencies and mainly to a characterisation of the evolution steps in knowledge and action organisation from novice to expert. Eight grown-up preparing a professional certificate in engine mecanics were observed and filmed while they were working out the diagnosis of an ignition trouble on a real equipment. The theory of functionning registers (deducted from Piaget’s theory) is considered as a relevant frame for our activity analysis. So, four competencies patterns has been outlined on the basis of errors extension, circuit functionning representations which were infered from schema interpretations, and trouble-shooting strategies denoted by control procedures. Some consequences about training are examined. 相似文献

The purpose of this study was to investigate how children aged five to nine gradually build up an understanding of the characteristics of place-value inherent in the written number system. The task consisted in presenting collections of chips, asking children to produce the corresponding two-digit numerals, and then questioning them in a structured clinical interview about the possible numerical meaning (in terms of correspondence to a number of chips) of each of the digits in the numeral. Results show that the idea that parts of the notation must correspond to mutually exclusive parts of the collection is but slowly built up, and that subsequently it is fleshed out by the use of knowledge concerning oral numeration_— written numeration correspondences. Intuitions concerning «groups of ten» arise later. A fair proportion of eight-year-olds and all nine-years-olds saw the two-digits as corresponding to, on the one hand, a number of units, and on the other, a number of groups of units. 相似文献

ABSTRACTThe potential relationships between innovation and sustainability processes, in engineering education, is neither obvious nor simple, especially when innovation, generally speaking, is promoted regardless of sustainability. We used UniLaSalle (In January 2016, the ‘Institut Polytechnique LaSalle Beauvais’, a French engineering school, merged with another higher education engineering school (ESITPA, Rouen). Both campuses (Beauvais and Rouen) have a common name: UniLaSalle (www.unilasalle.fr). As the interview began during 2015, this article only describes the situation of the Beauvais campus.) as a ‘living Lab’ to identify and analyse the reasons for the integration of innovation and Sustainable Development (SD) in training programmes. The aim is to explore, in a perception and reflective approach, how SD can be understood as a driver for specific innovation attitudes in higher education engineering school. This paper adopts an empirical approach based on a qualitative study, using NVivo 9 software to analyse non-numerical data. Our research suggests that SD can be a structural driver for innovation if it is integrated in a transdisciplinarity approach and not just as a discipline per se. 相似文献
